I decided to make them either treaded or hoverers with a tank-like turret on top, but I am leaning toward the hovercraft design.
The design scheme I had in mind was very sharp, angular, and definitely not something most humans would enjoy being in close proximity too.
Ideally, I want them to be both visually and practically distinct from the other two teams, so hovering would probably be the best bet, not to mention they can be much more lacking in animations if one is feeling lazy.
